Application filed April 22. 1918. Serial No. 230.073.

To aZZ'wwm t may concern.'

lBe it -known thatI, EDWIN A. REETZ, a citizen of "the United States,residing at Hooper, in the coun-ty of Dodge and State of Nebraska, haveinvented certain new and useful improvements in Hoisting Mechanism, of-which the following Vis a specification, rreference being had to theaccompanying'-dra-wings.

' t' This invention relates toicertain improvemerits'in hoisting boxesonl wagons or trucks and 1t is" an obJec't of the invention to `providel'a device of Athis 'general cha'ra'cter havnovelandimproved meanswhereby-fthe body-'of l[the Wagon` or truck maybe ireadily andconvenientlyfmoved o-r ftilted into dumping position.

it 'is-also aanbiedt ,of the' invention to `provide a novel andimproved-'device of 'this general character vhaving ymeans for'imparting the requisite movement I'to the body of fthe wagon 4orA"truck, said l-means including la i mechanism -which renders said`means norv mallyinop'eraitive. y

'1- Another obj ectof the invention is `to' 'provide a novel and'improved device 'of this,v eneral character including al body mounted'or swinging movement in a lvertical plane together 'with `means forcausing said body to -assume a tilting.. position and whereinv means areemployed for retarding the return movement of the body. 'lV

The invention consistsV in thexdetails of construction and in the'combination and arrangement of the several parts of my improved 'hoistwhereby certain important advantages are attained and the device' ren'-dered simpler, less expensive and otherwise more convenient andadvantageous for use, as will be hereinafter more fully set forth. Thenovel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accompanying drawingswherein:

Figure 1 is a view in side elevation illustrating a hoist constructedin4 accordance with an embodiment of my invention;

Fig. 2 is a fragmentary view in elevation illustrating the mounting ofthe mast or standard as herein employed;

Fig. 3 is a fragmentary View partly in section and partly in top planvillustrating -the vconnection of the 'swinging body with the mast orstandard;

Fig. `l is a View partly in 'elevation and partly in sectionillustrating the means for raising` or tilting :the wagonor truck body;

',The bodyjis capable `of swinging movement in a 'verticalplane. -The flower portion of the body Bl at thelforward end j 'thereofis provided with a pair 'ofspaced guide "arms or members 7 havingsliding engagement with a mast or standard. ,The

forward end of the body B between the arms or members 7 is also providedwith the outwardly directed lug 8 or theliketo which is suitably engagedan end portion of a exible member M.: The member M is disposed over theupper pulley 5 and then around thev lower pulley 5. From the lower endportion of the mast or standard 3 the member M extends rearwardly and isengaged with the winding drum D suitably supported bv the frame F andmounted for movement around a vertically disposed axis. Upon rotation ofthe drum D in one direction the member M is wound therearound whichresults in an elevation of the forward end portion of the body B wherebysaid body is moved into dumping position.

The central portion of the drum D is provided withy a| worm gear 9yadapted*l to be engaged by the Worm 10 carried by the shaft 11. An endportion of,thezshaft'511 is prof vided With an operating crank 12whereby the desired rotation may be imparted to the shaft 11. The shaftll1 is disposed transw versely of the frame F and is rotatably supportedby the rotatable bearings 14 suitably supported by the frame F.'The'shaftll is eccentric-to they. axes Aof the-bearings 14 so that upon=movement of ethefbearings V14: f in oned-iretion.,theJvormflO will be.disen- Y gaged from the'gear, andvice versa'.
